detailed description

Embodiment 1, as shown in FIG. 1 and FIG. 2, a shower having a function of rotating water, the water inlet passage 100 is located at the top of the entire shower, and the input port 101 is located at a position where the shower is screwed at the time of installation; The input water flow of the input port 101 flows through a ball head 103 to a splitter box 110, and is output from its output port 112, which is a complete water flow path for the water inlet passage 100. The presence of the splitter box 110 allows a single stream of water from the input port 101 to be output in accordance with the number of output ports 112. In this example, "upper" and "lower" are defined as the order of flow through the waterway, with the first passer being above and vice versa.

The water outlet terminal 200 is located at the lower end of the water passage of the water inlet passage 100, and is switched to be electrically connected to the outlet port 112 through both the rotation inlet 301 and the synchronization inlet 215 on the water distribution tray 220 to constitute two different water passages. The rotation inlet 301 and the synchronization inlet 215 are rotatably fitted to the output port 112 in a plane on the top surface of the water distribution tray 220.

In addition, the synchronization inlet 215 and the rotation inlet 301 are rotationally symmetrical with respect to the output port 112 on the top surface of the water distribution plate 220 and the output port 112. As can be seen from the figure, the same rotation axis is bilaterally symmetrical, so that the water distribution plate 220 can be made. Rotation, the output port 112 is switched to turn on the synchronous inlet 215 or the alternate inlet 301. In particular, by rotating the water diversion tray 220, when the output port 112 conducts the rotation inlet 301, the owners of the synchronization inlet 215 are mutually The seals are cut off and connected to the waterless road. This arrangement makes the waterway switching clear and clear and does not interfere with each other.

At the lower end of the waterway of the water distribution tray 200, there are a rotating chamber 300 and two rotationally symmetric water outlet chambers 210 in sequence; the rotating chamber 300 is coaxial with the axis of the shaft of the water outlet chamber 210, and has the same rotationally symmetric structure. The shape of the water outlet chamber 210 is a flat space which is independent of each other, and has a rotating water inlet hole 213 at the center of the shaft center, and the above-mentioned synchronization inlet 215 is located at the outer circumference of the rotation water inlet hole 213; the water outlet chamber 210 also has a plurality of water outlets The holes 211, the plurality of water outlet holes 211 are the shower head forms on the shower surface.

The upper end of the rotation chamber 300 has the above-mentioned rotation inlet 301, and the inside is a hydraulic rotation device 310. When the rotation inlet 301 and the output port 112 are electrically connected, the water flow from the outside of the shower can impact the hydraulic rotation device 310 in the rotation chamber 300, thereby The water flow is alternately introduced into the lower rotating water inlet hole 213, because at the same time, the synchronous inlet 215 which is also connected to the water outlet chamber 210 is blocked, so that the water outlet chamber 210 is alternately filled with water flow so that it can only be rotated from the respective water outlet holes 211. The ground is ejected, which realizes the function of rotating water. It can be seen that under this structure, all the water outlet holes 211 can be set to participate in the two states of synchronous water discharge and wheel water discharge, and the entire water outlet surface can be switched over the entire area, so the rotation effect is very good, and the water passage brought by the rotation. At the same time, the operation of switching out of the water chamber 210 for synchronous water discharge or rotation of water is achieved by the entire water outlet terminal 200 rotating back and forth at a certain angle, which is very convenient and reliable. Of course, the water dividing tray 220 can in fact be combined with the output port 112 in many ways, such as spherical sliding, parallel sliding, etc., as long as the function is ensured - the rotating inlet 301 and the output port 112 are turned on, the synchronous inlets 215 are mutually It can be cut off. Because of such an arrangement, the switching structure is simplified. At the same time, as shown in the figure, although the water outlet chamber 210 is two-rotation symmetry in this example, it can be conveniently expanded into a plurality of required water-out chambers 210 in a rotationally symmetric form. In order to achieve more ways of rotation.

3 is another perspective view of the embodiment of FIG. 1; FIG. 4 is an exploded perspective view of the hydraulic rotation device 310 of the embodiment of FIG. 1; FIG. 2, FIG. 3 and FIG.

The water outlet chamber 210 is mainly formed by the shower panel 205 and the upper cover 204, and the rotation chamber 300 is also formed on the upper end of the upper cover 204. The upper cover 204 and the panel 205 are fixed to the water distribution tray 220, and the same is fixed. A coaxial decorative cover 209.

The hydraulic rotation device 310 includes a reduction gear 311 that is driven by the torque generated by the water flow impinging on the impeller 312. After the water flow of the output port 112 in Fig. 1 enters the rotation inlet 301, it is converted into a water flow having circumferential kinetic energy through a slanting water body 303, and the impeller 312 is rotated.

The speed reducing device 311 is a mechanism of a planetary gear train. As can be seen from FIG. 4, the lower end of the impeller 312 is fixed to a coaxial sun gear 313, centered on the sun gear 313, having three symmetrically engaged planet wheels 314, and the outer circumference of the planet gear 314 has a planet carrier 315, the planet carrier 315 is in the form of internal teeth formed on the inner circumference of the rotating chamber 300 on the upper cover 204; the rotating shafts of the three planetary wheels 314 are simultaneously located on one water stopping piece 320. It can be seen that the high-speed rotation of the sun gear 313 transmits the low-speed rotation of the water piece 320, and the water stop piece 320 is slidably fitted to the rotation water inlet hole 213, and the rotation thereof achieves the rotation conduction of the rotation water inlet hole 213 and the rotation cavity 300. . By utilizing the advantages of the planetary gear reduction mechanism, the hydraulic rotation device 310 has the characteristics of low noise, stable rotation speed, and relatively stable torque, and in particular, the rotation inlet hole 213 is concentrated on the entire central portion of the upper cover 204 and the panel 205, so as to stop The water piece 320 can realize the rotation and conduction with a small torque, and the device has a compact structure, and the rotation force is reasonable and stable.

Figure 5 is a cross-sectional view showing the operation of the embodiment of Figure 1 in a rotated state; and Figure 6 is a cross-sectional view showing the operation of the embodiment of Figure 1 in a normal state. The working state of this embodiment will be described again in conjunction with these two figures:

In Fig. 5, the water from the input port 101 passes through the splitter box 110 and flows out of the output port 112. At this time, the output port 112 and the rotation inlet 301 are electrically connected thereto, so that the water flows through the oblique water body 303, and the rotation of the water stop piece 320 is stopped. Underwater, it alternately enters the two water outlets 210, and finally divides the water outlet hole 211 from the entire shower water surface into two parts and rotates to realize the massage water flow with the effect of the thumping massage; FIG. 6 can be based on FIG. The hand-held decorative cover rotates to make the synchronous inlet 215 and the output port 112 conductive. Since the synchronous inlet 215 is kept in communication with the water outlet chamber 210, the water flow from the input port 101 can flow out synchronously from all the water outlet holes 211 without obvious obstacles. Realize the basic functions of the shower. It can be seen that the structure for realizing these switching is simple and the operation is very convenient.

Embodiment 2, as shown in FIG. 7, a shower having a function of rotating water, which differs from Embodiment 1 in that: three outlets 210 are arranged, and the synchronization inlets 215 are circumferentially distributed in the rotation. The outer circumference of the water inlet hole 213 is correspondingly provided with three water outlet areas (please refer to FIG. 1) .

Embodiment 3, as shown in FIG. 8, a shower having a function of rotating water, is different from Embodiment 1 in that: four outlets 210 are arranged, and the synchronization inlets 215 are circumferentially distributed in the rotation. The outer circumference of the water inlet hole 213 is correspondingly provided with four water outlet areas (please refer to FIG. 1) .

The above is only the preferred embodiment of the present invention, and thus the scope of the present invention is not limited thereto, that is, equivalent changes and modifications made in accordance with the scope of the invention and the contents of the specification should still be covered by the present invention. Within the scope.
